Syntax

LIBNAME(libref<,SAS-data-library<,engine<,options>>>)

libref: specifies the libref that is assigned to a SAS library. Under Windows, the value of libref can be an environment variable.
SAS-data-library: specifies the physical name of the SAS library that is associated with the libref.
engine: specifies the engine that is used to access SAS files opened in the data library.
options: names one or more options honored by the specified engine, delimited with blanks.

Details

If the LIBNAME function returns a 0, then the function was successful. However, you could receive a non-zero value, even if the function was successful. A non-zero value is returned if an error, warning, or note is produced. To determine whether the function was successful, look through the SAS Log and use the following guidelines:

If a warning or note was generated, then the function was successful.
If an error was generated, then the function was not successful.

Under Windows, if you do not specify a SAS-data-library or if you specify a SAS-data-library as ' ' (a space between single quotation marks) or '' (no space between single quotation marks), SAS deassigns the libref.
